Ubuntu 10.10 lost network after installing VBLinuxGuestAdditions

Description

Hello,

Yesterday I found an amazing fix for resolution of my monitor by installing guest additions of virtualbox. It helped, now I have dinamyc resolution here but I losted all network connections with host system. It worked before, ubuntu initialized it on installation, I tested system upgrade, web-surfing and everything worked perfectly. But after installing that modules all types of adapters doesn't work correctly.
I'm attaching my VB log, let me know if I need post here anything else.
